Abstract

An approach to applying design of experiments to multi-layer optical coating processes was explored. Two small designed experiments were first performed to determine the effect of process parameters on optical properties of silicon nitride and silicon dioxide single layer films. These results were used to predict the optimum operating region for the production of multi-layer dielectric mirror. A third experiment was then performed to test the prediction. The results of these experiments showed that while a quantitative optimization of the multi- layer process based on the single layer experiments was not possible; it was possible to qualitatively determine a region of parameter space for optimum mirror performance based on the single layer experiments.
